At this point, you can see the remains of wood used by the aizkolaris (axe-wielding log cutters). There is also a statue honoring the aizkolari women, with a text on its back in Basque that means "Women have always cut wood."

That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.
